Detailed Description
As shown in fig. 1, 2 and 3, the utility model relates to a steering gear pull rod wrench, which is used for dismounting the pull rod of an automobile steering gear, comprising an outer sleeve 2 and an inner sleeve 8, a plurality of claws 1 are arranged around the inner sleeve 8, the inner sleeve 8 and the claws 1 are arranged in the outer sleeve 2, and the inner sleeve can move axially relative to the outer sleeve 2. The structure of the pull rod of the direction machine comprises a rod body 6 and a ball head 5 positioned on the rod body 6, wherein a polyhedron 4 is arranged below the ball head 5 and used for twisting and rotating to complete the disassembly and assembly of the pull rod. When jack catch 1 removed to the overcoat 2 front end outside, the front end of jack catch 1 can outwards open, with the spanner suit on the pull rod, jack catch 1 can the cladding in the bulb 5 outside. The rear end of the outer sleeve 2 is provided with a hollow extension rod 3, and the extension rod 3 and the outer sleeve 2 are radially fixed. The extension rod 3 can completely wrap the rod body 6, so that the rod body 6 is prevented from being damaged during disassembly and assembly. When the jack catch 1 moves into the outer sleeve 2, the front end of the jack catch 1 holds the ball head 5 tightly. The front end of the clamping jaw 1 is provided with an inner shoulder 1.2, the inner shoulder 1.2 forms a torque head when the front end of the clamping jaw 1 is held tightly, and the torque head can be held tightly with a polyhedron 4 below a ball head 5, so that a pull rod can be rotated by a wrench.
As shown in fig. 4 and 5, the number of the claws 1 is 3 or 4, and the claws are uniformly distributed in a ring shape. The rear end of the clamping jaw 1 is installed on an installation part 8.2 of the inner sleeve 8, an elastic ring 7 is sleeved at the rear end of the clamping jaw 1, the rear end of the installation part 8.2 is a conical surface 8.3 with a large front part and a small rear part, the restoring force of the elastic ring 7 enables the rear end of the clamping jaw 1 to be attached to the conical surface 8.3, and the front end of the clamping jaw 1 is outwards opened.
