Abstract

The utility model relates to a modification of a screwdriver structure, which is mainly composed of a handle, a clamping stopper and a tool rod, wherein, the handle is provided with an inserting hole in the main body, the clamping stopper presents a hollow through hole, while a propping part is arranged on the main body, a consolidating part is arranged through the propping part extending backward, and a clamping stopper segment of an inclined guiding surface is arranged at the end of the consolidating part, a clamping stopper groove and a chamfering segment are arranged at the end section of a inserting rod, the chamfering segment of the inserting rod can be exactly propped against the clamping stopper segment, thus the clamping stopper segment can strut externally under the stress and can prop in the clamping stopper groove to limit the position, and then the inserting and operation of the tool rod can be achieved, on the contrary, when the tool rod is inserted and changed, the clamping stopper segment is under the stress, thereby the clamping stopper groove can be propped against the inclined pushing surface of the clamping stopper segment, to ensure that the clamping stopper segment can strut externally and depart from the clamping stopper groove, and then the tool rod can be inserted outwards and replaced, thereby achieving the modified structure of the screwdriver with the easy replacement of the tool rod and the convenient carrying of the screwdriver.

Description

The screwdriver structure improvement

Technical field

The utility model is relevant a kind of screwdriver structure improvement, refers to a kind of screwdriver structure improvement that is easy to change tool bar especially.

Background technology

Press, general traditional bottle opener mainly is to set firmly a tool bar in the holding rod front end, the front end of tool bar has just like yi word pattern, the tool heads of cross or hexangle type or the like different size, with in response to being used on the different operating occasion, but because only can corresponding a kind of specification on every holding rod and the tool heads of size, but because of the required difference in workplace, and need are prepared the tool heads of all size and size, be the inconvenience of carrying and using to cause, and the utmost point takes up space and increases the cost of choosing tool, therefore, the various inconvenience of instrument dealer in response to aforementioned bottle opener instrument are promptly arranged, be to research and develop out the holding rod front end to set firmly a tool bar, this tool bar front end then is provided with the jack that can supply tool heads to plug, so, can be by the setting of jack, and but the tool heads of different size and size plugs, to solve above-mentioned carrying and problem that cost is high, but also being arranged at the front end of tool bar because of this jack, being subject to the function that the bottle opener tool bar itself carries, is the setting with jack, make the wall thickness attenuation of tool bar itself, and then making this tool bar plug the torque value variation of being born behind the screwdriver head, it is stressed and influence, and then is not suitable for the workplace of high twisting resistance.

Edge this, the creator of this case is engaged in various bottle opener instrument design and manufacturing experience for many years based on it, in view of the existing high torsion of bottle opener and be convenient for carrying the awkward situation that to take into account, and the degree of difficulty of raising site operation is actively studied improvement, and the phase can provide the device of a simple and easy replacing tool bar, in the time of can reaching site operation, the bottle opener that is convenient for changing and carries via test and change repeatedly, gets generation of the present utility model eventually.

The utility model content

Main purpose of the present utility model is the clamping piece that sets firmly a tool clamping function in by handle, and can supply plugging of different size tool bar in this clamping piece, and can reach the screwdriver structure improvement of changing tool bar.

The utility model provides a kind of screwdriver structure improvement, and it mainly is made up of a handle, a clamping piece and a tool bar, it is characterized in that, wherein:

One handle is to be provided with an inserting hole in a body;

One clamping piece is to be the hollow open-work, and a blocking part is set on its body, extends a fixed portion in this blocking part backward, and the clip section of an inclined thrust surface then is set in this fixed end;

One tool bar is in its lever front end one tool heads to be set, and an end that differs from tool heads then is provided with one and plugs bar, and this latter end that plugs bar then is provided with a clip groove and chamfering section.

Wherein, the clip section of this clamping piece is to be more than one to be provided with.

Wherein, the clip section of this clamping piece is to be more than two or two to be provided with.

Wherein, this tool heads is to be the setting of corresponding polygonal shape with plugging bar.

Wherein, this clamping piece is to be coated in the handle inserting hole with ejection formation in its fixed portion.

The beneficial effects of the utility model are:

Screwdriver structure improvement of the present utility model, it is by the clamping piece that sets firmly a tool clamping function in the handle, and can supply plugging of different size tool bar in this clamping piece, and can reach the effect of changing tool bar.

The specific embodiment

See also Fig. 1～shown in Figure 3, the utility model mainly is made up of a handle 1, a clamping piece 2 and a tool bar 3, wherein:

One handle 1 is to be provided with an inserting hole 11 in a body;

One clamping piece 2 is to be hollow open-work 21, and a blocking part 22 is set on its body, extends one fixed 23 in this blocking part 22 backward, and the clip section 24 of a tool inclined thrust surface 241 then is set in this fixed 23 end;

One tool bar 3 is in its lever front end one tool heads 31 to be set, and an end that differs from tool heads 31 then is provided with one and plugs bar 32, and this latter end that plugs bar 32 then is provided with a clip groove 321 and chamfering section 322.
