Abstract

The utility model discloses a kind of jaw type drive shaft extracting tool, it is characterized in that, including two clamps, each clamp includes short support arm and long support arm, short support arm and long support arm is V-shaped is connected, two clamps are hingedly fixed in together in bending part, and the binding clip of arc is extended with the short support arm of each clamp.The utility model increases the contact area of extracting tool and inner sliding sleeve by the binding clip of arc, and the abrasion to drive shaft is avoided by the way of multiple spot stress, meanwhile, the mode of multiple spot stress is less likely to occur to slide, more securely and reliably.

Description

A kind of jaw type drive shaft extracting tool

Technical field

It the utility model is related to car disassembly instrument, and in particular to a kind of jaw type drive shaft extracting tool.

Background technology

Changed in the maintenance of drive shaft, and in the maintenance work of vehicle, it is often necessary to by drive shaft from gearbox, slow down Pulled down on case.The attachment structure that most drive shaft is all coordinated using jump ring with bevel gear in the market.

Existing conventional tool uses crowbar, and the fulcrum of crowbar is the housing of gearbox, and crowbar impetus is in drive shaft Sliding sleeve.During dismounting, housing and inner sliding sleeve single-point stress, surface crushes easily；Inner sliding sleeve one side stress, easily extrudes sliding sleeve Deformation, or even cause the bearing of differential mechanism to release or other damage of components；Worker is exerted a force using impact during dismounting, is easily caused Injury to personnel.

Utility model content

The utility model purpose is to provide for a kind of convenient disassembly and will not damage the extracting tool of drive shaft.

To achieve these goals, the utility model uses following technical scheme：A kind of jaw type drive shaft extracting tool, bag Include two clamps, each clamp includes short support arm and long support arm, short support arm and long support arm is V-shaped is connected, and two clamps exist Bending part is hingedly fixed in together, and the binding clip of arc is extended with the short support arm of each clamp.

Further, the long support arm of each clamp is telescopic motion bar.

Further, it is connected with constriction device between two long support arms.

Further, constriction device is one kind in hydraulic jack or electric pushrod.

The utility model increases the contact area of extracting tool and inner sliding sleeve by the binding clip of arc, using multiple spot stress Mode avoid the abrasion to drive shaft, meanwhile, the mode of multiple spot stress is less likely to occur to slide, more securely and reliably.

The utility model increases the application torque of operator by the long support arm of adjustable length, and convenient adaptation is different Dismounting demand.

The utility model also replaces manpower by the constriction device, more safe and efficient.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is Fig. 1 right view.

Embodiment

The technical solution of the utility model is further elaborated with reference to specific embodiment.

A kind of embodiment of jaw type drive shaft extracting tool as shown in Figure 1, including two clamps 1, each clamp 1 wrap Include short support arm and long support arm, short support arm and long support arm is V-shaped is connected, two clamps 1 are be hinged solid by bearing pin 3 in bending part It is scheduled on together, semicircular binding clip 2 is extended with the short support arm of each clamp 1.

The application torque of increase operator for convenience, the long support arm of each clamp is telescopic motion bar.

Constriction device 4 is connected between the long support arm of two clamps 1, constriction device 4 is from hydraulic jack or electronic One kind in push rod, constriction device are used for replacing manpower, and constriction device 4. can be used when manpower can not complete installation

This is prior art using NM technology in new.

The present embodiment is optimum embodiment, the foregoing is only the preferable specific implementation of technical solutions of the utility model Example, rather than the restriction to technical solutions of the utility model, any those of ordinary skill in the art for being familiar with the technology are in this reality With the variations and alternatives that in new suggested technical scope, can be made without creative thinking, should all cover at this Within the protection domain of utility model right requirement.
