Abstract
The utility model discloses a kind of screw-in hold-down mechanism, comprise chuck and screw handle, the described handle that screws comprises top cover and round bar, described round bar one end is connected with threaded rod, described chuck consists of a nahlock and three fixing feet, and described chuck is provided with through hole, and described threaded rod is provided with external screw thread, corresponding, in described through hole, be provided with internal thread.The beneficial effect of technique scheme of the present utility model is as follows: 1) solved and stepped up position problem devious at every turn; 2) saved operating space; 3) potential safety hazard of hurting sb.'s feelings after having stopped to open.
Description
Technical field
The utility model relates to a kind of hold-down mechanism, refers to especially a kind of screw-in hold-down mechanism.
Background technology
If stepping up on part is in the past a little far away apart from edge, employing be extension bar to be installed on clamp realize and stepping up, the long meeting of extension bar causes stepping up position at every turn deviation, after opening, has potential safety hazard, and extension bar can affect measurement space.As shown in Figure 1, traditional mode of stepping up, extension bar length is more than 300mm, and the long meeting of extension bar causes termination to swing seriously stepping up, after mechanism opening 120 degree, to have very large potential safety hazard, brings very large constant for remaining operation
Utility model content
The technical problems to be solved in the utility model is to provide a kind of screw-in hold-down mechanism.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of screw-in hold-down mechanism, comprise chuck and screw handle, the described handle that screws comprises top cover and round bar, and described round bar one end is connected with threaded rod, and described chuck consists of a nahlock and three fixing feet, described chuck is provided with through hole, described threaded rod is provided with external screw thread, corresponding, in described through hole, be provided with internal thread.
As preferably, the diameter of described round bar is less than the diameter of described through hole.
As preferably, described nahlock and described fixing feet are one-body molded.
As preferably, described top cover, round bar and threaded rod are one-body molded.
The beneficial effect of technique scheme of the present utility model is as follows: 1) solved and stepped up position problem devious at every turn; 2) saved operating space; 3) potential safety hazard of hurting sb.'s feelings after having stopped to open.

The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As described in Fig. 2-4, the utility model provides a kind of screw-in hold-down mechanism for existing deficiency, comprise chuck 1 and screw handle 2, the described handle that screws comprises top cover 21 and round bar 22, and described round bar 22 one end are connected with threaded rod 23, and described chuck 1 consists of a nahlock 11 and three fixing feet 12, described chuck 1 is provided with through hole 3, described threaded rod 23 is provided with external screw thread, corresponding, in described through hole 3, be provided with internal thread.
The diameter of described round bar 23 is less than the diameter of described through hole 3.
Described nahlock 11 is one-body molded with described fixing feet 12.
Described top cover 21, round bar 22 and threaded rod 23 are one-body molded.
There is the position of stepping up a little in the surrounding that this concrete enforcement is applicable to hole on part, as accessory in Fig. 51 screws in the hole 4 that handle gos deep into part, coordinate and screw with screwed hole on the body simulated block of part below, make chuck step up the strong point 5 of part below, after measurement completes, only need to turn on handle, vacancy is left in Jiang Ci mechanism.
This concrete enforcement is torqued into the threaded rod 23 of rotating handles 2 terminations in the through hole 3 of chuck 1, and after threaded rod 23 passes, through hole 3 that round bar 22 can be on chuck 1 is interior freely walks, and mentions like this chuck and handle after handle and can not come off.
This concrete enforcement has solved and has stepped up position problem devious at every turn; Saved operating space; Stopped the potential safety hazard of hurting sb.'s feelings after opening.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
