Abstract

The utility model discloses a countersunk bolt for pressing a wire. The countersunk bolt for pressing the wire comprises a bolt head and a threaded rod, wherein spiral threads are formed in the threaded rod, a line-shaped through groove is formed in the bolt head, and the end face of the bottom of the threaded rod is round. The countersunk bolt for pressing the wire has the advantages that due to the fact that the threaded rod is provided with the round end face, the circuit wire cannot be easily damaged when the countersunk bolt is used for pressing the wire; due to the facts that a nut is omitted, and the bolt head is directly used, the structure can be simple; in addition, due to the fact that the line-shaped through groove is formed, the countersunk bolt for pressing the wire is convenient to install and better in applicability.

Description

Countersunk screw for line ball
Technical field
The utility model relates to a kind of bolt field, especially for the countersunk screw of line ball.
Background technique
At present, electric wire on the circuit elements device generally fixes with wire clip, but electrical wire clip can't be used when space is less, so line pressing bolt just occurred on the market, the tip of screw can damage electric wire when line ball, and the nut of screw is exposed can take up room, affect laying of other devices outside device.
Summary of the invention
The purpose of this utility model is to provide a kind of countersunk screw for line ball that does not damage the circuit line in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the countersunk screw for line ball that the utility model is designed, comprise spiral shell head and screw rod, described screw rod is provided with spiral helicine screw thread, in order to coordinate " one " font screw-driver of various models, described spiral shell head is provided with " one " font groove, and in order in use not damage the circuit line, described screw rod bottom end face is circular.
The countersunk screw for line ball that the utility model obtains, thereby its technique effect is the circular end surface not fragile circuit line when line ball by screw rod, and having saved nut, directly to adopt the spiral shell head to make simple in structure, " one " font groove makes this bolt be convenient to install in addition, and applicability is wider.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 the countersunk screw for line ball.
In figure: spiral shell head 1, screw rod 2, screw thread 3, groove 4.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1:
As shown in Figure 1, the countersunk screw for line ball that the present embodiment provides, comprise spiral shell head 1 and screw rod 2, and described screw rod 2 is provided with spiral helicine screw thread 3, and described spiral shell head 1 is provided with " one " font groove 4, and described screw rod 2 bottom end faces are circular.In concrete using process, when the needs line ball, this countersunk screw is put into to screw, then with screw-driver, to aim at 4 rotations of " one " font groove and be screwed into, the spiral shell head 1 after making to screw is not higher than the surface of device.
