The spring installation fixture in the utility model can safely and easily complete the moveable handle return spring installation, effectively preventing an operator from being hurt and the scrapping of the product.
Description
Technical field
The utility model relates to a kind of frock, relates in particular to a kind of spring frock is installed.
Background technology
In medical device industry, the problem of installing at the difficulty of the flexible handle back-moving spring of PPH and tubular digestive tract stapler is not well solved always.Installation method commonly used at present is that " one " font screwdriver is worn into " V " font.Use the screwdriver of " V " font to push away the free end of back-moving spring then, snap into boss back on the flexible handle until the free end of back-moving spring.This method all has very high requirement to the skill and the qualification of installing, and the elastic force of adding back-moving spring is very big, and installation personnel is difficult to control direction, the phenomenon of " V " font screwdriver landing from the back-moving spring usually occurs.In a single day in operating process, landing occurs, be easy to stab oneself, or stab product surface, thus the industrial injury of causing or product rejection.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of and can finish the spring that the flexible handle back-moving spring installs safely, like a cork frock is installed, and it has effectively avoided operating personnel injured or make product rejection.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of spring is installed frock, comprise the bar shaped handle, the side face of described bar shaped handle is provided with projection, has breach on the described projection, and described breach is arranged at projection and goes up on the one side on bar shaped handle top.
Further, described bar shaped handle one end is provided with the supporting head part of a projection along its length direction, and spring is installed frock so just a rotating fulcrum.
Further, described breach journey " V " font, it is arranged at projection and goes up on the one side of supporting head part, and " V " type breach has been arranged, and just can firmly block the free end of back-moving spring.
The beneficial effects of the utility model: the utility model has solved the defective that exists in the background technology, what this frock adopted is lever principle, has tangible labor-saving effect, thereby improved the control difficulty that causes because of big operating physical force, and the strength to operating personnel is less demanding, and men and women employee all can operate.The application of lever principle makes installation process safer, can frock landing and cause industrial injury or damage product from the back-moving spring be installed because of spring.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation that spring is installed the preferred embodiment of frock;
Fig. 2 is the perspective view that spring is installed the preferred embodiment of frock;
Fig. 3 is the structural representation of back-moving spring tubular digestive tract stapler when not installing;
Fig. 4 is the structural representation that back-moving spring installs the tubular digestive tract stapler in back.
Wherein: 1, bar shaped handle; 2, projection; 3, breach; 4, supporting head part; 5, tubular digestive tract stapler; 51, back-moving spring; 52, back-moving spring pin; 53, flexible handle boss.
The specific embodiment
A kind of spring is as shown in Figure 1 and Figure 2 installed frock, comprises that cross section is rectangular bar shaped handle 1, and the side face of this bar shaped handle 1 is provided with projection 2, has " V " font breach 3 on the projection 2.Bar shaped handle 1 one ends also are provided with the supporting head part 4 of a projection along its length direction, and this supporting head part 4 is an arc-shaped head.Described breach 3 is arranged on the projection 2 on the one side of supporting head part 4, described protruding 2 and supporting head part 4 between distance should be less than the flexible handle boss 53 of as shown in Figure 3, Figure 4 tubular digestive tract stapler to the distance between the back-moving spring pin 52.
Using method: the free end that earlier breach on the bar shaped handle 13 is blocked the back-moving spring 51 of tubular digestive tract stapler 5, compression reseting spring 51 makes the supporting head part 4 of bar shaped handle 1 prop up back-moving spring pin 52 then, then with supporting head part 4 be fulcrum firmly rotate free end that bar shaped handle 1 makes back-moving spring 51 to the direction of flexible handle boss 53 by going, when the free end alignment activity handle boss 53 of back-moving spring 51, direction trip spring along back-moving spring 51 elastic force is installed frock, and back-moving spring 51 just installs smoothly like this.
