referring to fig. 1-14, the present embodiment includes a handle 1, a blade 2 and a safety sheath 3, the handle 1 is composed of a handle 101 and a blade seat 102, and the lower end of the safety sheath 3 is provided with an anti-skid protrusion 10 for anti-skid. The knife handle 1 is made of nontoxic ABS or other materials meeting requirements, and the blade 2 is made of T10, Cr06 and stainless steel materials or other materials meeting requirements.
The blade 2 is provided with a mounting groove 7, the front end of the blade seat 102 is provided with a fixing bulge 8 matched with the mounting groove 7, and the mounting groove 7 is fastened and inserted on the fixing bulge 8, so that the blade 2 is fixedly mounted at the front end of the blade seat 102. As long as mounting groove 7 on blade 2 and fixed protruding 8 phase-match, blade 2 can be changed into various shapes as required, and blade 2 dismantles easily, can not block to die, too loose or fracture.
At the upper end of the blade seat 102 is provided a release button 4 connected thereto by a resilient cantilever arm 5. The blade seat 102 is provided with a convex sliding track 9, and the safety sheath 3 can slide along the sliding track 9, so that the safety sheath 3 is slidably sleeved on the blade seat 102. The sliding track 9, in addition to providing a guide for the safety shield 3 to slide, also increases the strength of the blade seat 102. The upper end of the safety sheath 3 is provided with a front locking groove 301 and a rear locking groove 302 which are matched with the release button 4, the front locking groove 301 is provided with a front elastic pressing strip 6 which extends towards the handle 101, and the rear locking groove 302 is provided with a rear elastic pressing strip 11 which extends towards the blade seat 102.
The using process of the scalpel is shown in fig. 15-18, and concretely comprises the following steps:
the initial state of the scalpel, i.e. the state of the scalpel when manufactured and assembled, is shown in fig. 5, with the blade 2 inside the safety sheath 3. At this time, the release button 4 is located in the rear locking groove 302 of the safety guard 3, that is, the release button 4 is locked in the rear locking groove 302, the safety guard 3 cannot slide along the blade seat 102, and the blade 2 is covered by the safety guard 3.
When the scalpel is required to be used, as shown in fig. 15, the rear elastic pressing strip 11 is pressed by a thumb, the rear elastic pressing strip is contacted with the release button 4, then the release button 4 is pressed down, the elastic cantilever 5 is pressed down, the release button 4 is pressed down into the safety sheath 3 from the rear locking groove 302 because the elastic cantilever 5 has certain elasticity, then the safety sheath 3 slides towards the scalpel handle 1, the release button 4 moves to the front locking groove 301 along with the relative sliding of the safety sheath 3 and the blade seat 102, the release button 4 bounces upwards under the elastic acting force of the elastic cantilever 5, the release button 4 is clamped in the front locking groove 301, a click sound is emitted at the moment, the safety sheath 3 cannot continuously slide along the blade seat 102, and the blade 2 is in an exposed state. As shown in fig. 10, the blade 2 is exposed from the safety sheath 3, and a scalpel can be used for operation.
After the scalpel is used, as shown in fig. 16, the front elastic pressing strip 6 is pressed by a thumb, because the front elastic pressing strip 6 has certain elasticity, the release button 4 is pressed downwards into the safety sheath 3 from the front locking groove 301 by the front elastic pressing strip 6, then the safety sheath 3 slides towards the blade 2, along with the relative sliding of the safety sheath 3 and the blade seat 102, the release button 4 moves to the rear locking groove 302, under the elastic acting force of the elastic cantilever 5, the release button 4 upsprings, the release button 4 is clamped in the rear locking groove 302, a 'click' sound can be emitted at the moment, the safety sheath 3 cannot continuously slide along the blade seat 102, and the blade 2 is in a state covered by the safety sheath 3. As shown in fig. 17, the scalpel now returns to its initial state shown in fig. 5, with the blade 2 inside the condom 3. Finally, as shown in fig. 18, the scalpel is placed into the waste container by holding the handle 101. The above operations can be completed by one hand.
Example 2:
referring to fig. 19-32, the present embodiment includes a handle 1, a blade 2 and a safety sheath 3, the handle 1 is composed of a handle 101 and a blade seat 102, and the lower end of the safety sheath 3 is provided with an anti-skid protrusion 10 for anti-skid. The knife handle 1 is made of nontoxic ABS or other materials meeting requirements, and the blade 2 is made of T10, Cr06 and stainless steel materials or other materials meeting requirements.
The blade 2 is provided with a mounting groove 7, the front end of the blade seat 102 is provided with a fixing bulge 8 matched with the mounting groove 7, and the mounting groove 7 is fastened and inserted on the fixing bulge 8, so that the blade 2 is fixedly mounted at the front end of the blade seat 102. As long as mounting groove 7 on blade 2 and fixed protruding 8 phase-match, blade 2 can be changed into various shapes as required, and blade 2 dismantles easily, can not block to die, too loose or fracture.
At the upper end of the blade seat 102 is provided a release button 4 connected thereto by a resilient cantilever arm 5. The blade seat 102 is provided with a convex sliding track 9, and the safety sheath 3 can slide along the sliding track 9, so that the safety sheath 3 is slidably sleeved on the blade seat 102. The sliding track 9, in addition to providing a guide for the safety shield 3 to slide, also increases the strength of the blade seat 102. The upper end of the safety sheath 3 is provided with a front locking groove 301 matched with the release button 4, and the front locking groove 301 is provided with a front elastic pressing strip 6 extending towards the handle 101.
The operating process of the scalpel is as follows:
the initial state of the scalpel, i.e., the state in which the scalpel is completely assembled during its manufacture, is shown in fig. 23, with the blade 2 positioned within the safety shield 3. At this time, the release button 4 is pressed inside the safety sheath 3, and the blade 2 is in a state covered by the safety sheath 3.
When the scalpel is required to be used, as shown in fig. 33, the safety sheath 3 slides towards the scalpel handle 1, the release button 4 moves to the front locking groove 301 along with the relative sliding of the safety sheath 3 and the blade seat 102, the release button 4 bounces upwards under the elastic force of the elastic cantilever 5, the release button 4 is clamped in the front locking groove 301, and then a click sound is generated, the safety sheath 3 cannot continuously slide along the blade seat 102, and the blade 2 is in an exposed state. As shown in fig. 28, the blade 2 is exposed from the safety sheath 3, and a scalpel can be used for operation.
After the scalpel is used, as shown in fig. 34, the front elastic pressing strip 6 is pressed down by a thumb, because the front elastic pressing strip 6 has certain elasticity, the release button 4 is pressed down into the safety sheath 3 from the front locking groove 301 by the front elastic pressing strip 6, then the safety sheath 3 slides towards the blade 2, along with the relative sliding of the safety sheath 3 and the blade seat 102, the release button 4 is pressed in the safety sheath 3 again, the safety sheath 3 cannot continuously slide along the blade seat 102, and the blade 2 is in a state of being covered by the safety sheath 3. As shown in fig. 35, the scalpel now returns to the initial state shown in fig. 23, with the blade 2 inside the safety shield 3. Finally, as shown in fig. 36, the scalpel is placed into the waste container by holding the handle 101. The above operations can be completed by one hand.
