Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment of the invention provides a knob pulling tool, which comprises a first shell 1, a second shell 2 and a connecting component 3, wherein the first shell 1 and the second shell 2 are oppositely arranged and form a cavity 4, and the first shell 1 and the second shell 2 are connected with the connecting component 3; thus, the first and second housings 1 and 2 are opened along the connection assembly 3, the knob to be pulled out is placed in the cavity 4, and then the first and second housings 1 and 2 are closed and pulled upward, pulling out the knob.
The bottom surfaces of the first shell 1 and the second shell 2 are respectively provided with a first half hole 11 and a second half hole 21, and the first half hole 11 and the second half hole 12 are matched to form a round hole 5 for fixing a knob valve rod to be pulled out, so that the knob valve rod is arranged in the round hole 5, and the damage to the knob valve rod is avoided.
The top surfaces of the first shell 1 and the second shell 2 are outwards extended to form a semicircular first pull lug 12 and a semicircular second pull lug 22, after the first shell 1 and the second shell 2 are closed, the first pull lug 12 and the second pull lug 22 are closed to form a circular pull lug 6, the first shell 1 and the first pull lug 12 are integrally formed, and the second shell 2 and the second pull lug 22 are integrally formed, so that the operation stress of a user is facilitated through the pull lug 6, and the pull force is smaller than that of a single pull knob.
The connection assembly 3 includes a support shaft 31, a first cylinder 32, and a second cylinder 33, the first cylinder 32 is sleeved on the support shaft 31 and connected with the first housing 1, the second cylinder 33 is sleeved on the support shaft 31 and connected with the second housing 2, and the support shaft 31 is a threaded pin, so that the first cylinder 32 and the second cylinder 33 drive the first housing 1 and the second housing 2 to move in opposite directions, and the first housing 1 and the second housing 2 are opened or closed.
Further included is a threaded plug 34, the threaded plug 34 being provided at the lower end of the threaded pin for limiting the first cylinder 32 and the second cylinder 33, the diameter of the threaded plug 34 being greater than the diameters of the first cylinder 32 and the second cylinder 33, so that the first cylinder 32 and the second cylinder 33 are prevented from sliding off the fulcrum 31 during use.
The using method comprises the following steps: as shown in fig. 4, first, the first cylinder 32 and the second cylinder 33 drive the first casing 1 and the second casing 2 to move in opposite directions respectively, so that the first casing 1 and the second casing 2 are opened, a knob to be pulled out is placed in a cavity 4 formed by the first casing 1 and the second casing 2, a valve rod is placed in a round hole 5, then the first casing 1 and the second casing 2 are continuously driven to be closed by the first cylinder 32 and the second cylinder 33, the pulling lug 6 is held and pulled upwards until the knob is pulled out, and the pulled knob is left in the cavity 4.
