Specific implementation mode
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, the technical solution of the utility model is described in detail.
A kind of internal expanding fixture comprising pressure head 1, gear bar 2, fixed block 3, handle 4, connecting plate 5, connecting rod 6, shaft 7,
Spring 8, telescopic rod 9 and locking knob 10, gear bar 2 are mounted on fixed block 3, are equipped with pressure head 1 in gear bar 2, pressure head 1 by
Gear bar 2 shrinks running, and handle 4 is located at 3 lower section of fixed block, shaft 7 is equipped on handle 4, and shaft 7 is connected with connecting rod 6,
Connecting plate 5 is fixed on 3 lower section of fixed block by connecting rod 6, and 5 top of connecting plate is equipped with spring 8 and telescopic rod 9, and spring 8 is located at reduction
9 outside of bar, 5 lower section dress of connecting plate is by locking knob 10.
In this example, 4 tail end of handle is equipped with rubber grips 11.
In this example, it is provided with non-slip texture 12 on pressure head 1.
In this example, detachable between locking knob 10 and connecting plate.
The operation principle of the utility model is as follows：Preferred pulling handle allows gear bar with dynamic head package as big as possible
The part fastened is needed, then handle inwardly pulls, and pressure head can be fastened on part both ends, then twists locking knob and further adds
Gu.
The utility model internal expanding fixture uses hand, and tension carries out locking to part close to the inner portion, can be effectively
Fixed function is played in miniature parts processing, at the same its is simple in structure, production efficiency can be improved using feature easy to carry and
Production cost.This internal expanding fixture in order to not easily to fall off when fixed, outside a locking knob is also mounted, it can be helped
The better retaining element of fixture reduces the dangerous situation caused by falling off.
Particular embodiments described above, the technical issues of to the solution of the utility model, technical solution and advantageous effect
It has been further described, it should be understood that the foregoing is merely specific embodiment of the utility model, not
For limiting the utility model, within the spirit and principle of the utility model, any modification for being made, changes equivalent replacement
Into etc., it should be included within the scope of protection of this utility model.
