It is suitable for use in canteens, restaurants, kitchens, meat stalls and slaughterhouses where fresh meat is cleaned and processed.
[0003] In order to be used multiple times, traditional shaving tools are designed with replaceable blades, that is, they include a handle and a blade clamp, one end of the blade clamp is fixedly connected to the handle; the blade clamp is made of a metal sheet folded in half and stamped, and the stamped metal sheet clamps and fixes the straight-blade shaving blade through the bite force. Although this straight-blade shaving tool has the function of replaceable blades and reduces the cost of use, during use, the blade can easily slip out of the gap of the blade clamp, the blade clamping and fixing are not stable enough, and the operating feel is not good. At the same time, the shaved hair, grease, dead skin and dirt can easily enter the gap of the blade clamp, which is not only difficult to clean, but also further affects the stability of the blade clamping and fixing of the blade. After a period of use, the bite force of the blade clamp will be reduced, and the gap will gradually become larger, making the above problems worse, seriously affecting the service life of the straight-blade shaving tool. Utility Model Content
[0004] The utility model aims to solve the deficiencies of the prior art and provide a shaving tool with replaceable blades. The shaving tool not only can replace the blades, but also has very stable clamping and fixing of the blades, good operating feel and long service life.
[0005] To solve the above problems, the following technical solutions are adopted:
[0006] The utility model discloses a shaving tool with replaceable blades, comprising a handle, a blade clamp fixed to the front end of the handle, and a shaving blade in the blade clamp. The utility model is characterized in that the lower end of the blade clamp has a blade slot, the inner edge of the front end of the blade slot has a first protrusion extending downward and inward, and the upper edge of the rear section of the blade slot has a second protrusion extending into the blade slot. The shaving blade is in the shape of an elongated strip, and the upper part of the front end thereof has a notch, and the inner bottom of the notch has a first groove, and the first groove is matched with the first protrusion. The upper part of the shaving blade near the tail end has a second groove, and the second groove is matched with the second protrusion.
[0007] The blade clamp includes a left clamp and a right clamp, and there is an intermediate fixing plate between the left clamp and the right clamp, and the three are fixedly connected, and the thickness of the intermediate fixing plate is equal to the thickness of the shaving blade. The upper edge of the intermediate fixing plate is flush with the upper edges of the left clamp and the right clamp, and the lower edge of the intermediate fixing plate is higher than the left clamp and the right clamp, so as to form the blade slot. The front end of the intermediate fixing plate extends downward and inward, so as to form the first convex point, and the rear section of the intermediate fixing plate has a downward convexity, so as to form the second convex point.
[0008] Furthermore, the rear end of the blade clip extends into the front end of the knife handle, and the two are fixedly connected. The lower front end of the knife handle has a clearance cavity for loading and unloading the shaving blade.
[0009] Furthermore, the handle is composed of a left handle unit and a right handle unit, and the left handle unit and the right handle unit are fixedly connected by rivets or bolts.
[0010] Furthermore, the tail ends and middle parts of the left handle unit and the right handle unit are connected by rivets or bolts, the front ends of the left handle unit and the right handle unit are connected by bolts, and there are arc notches on the middle fixing plates corresponding to the bolts at the front ends of the left handle unit and the right handle unit.
[0011] In the above solution, a third groove is provided at the lower portion of the tail end of the shaving blade. In the installed state, the lower portion of the third groove is located outside the lower edge of the blade clamp.
[0012] The above solution has the following advantages:
[0013] The blade holder of the utility model of the replaceable blade shaving tool has a blade slot at the lower end, the inner edge of the front end of the blade slot has a first convex point extending downward and inward, and the upper edge of the rear section of the blade slot has a second convex point extending into the blade slot; the shaving blade is in the shape of a long strip, the upper part of the front end thereof has a notch, the inner edge bottom of the notch has a first groove, and the first groove matches the first convex point; the upper part of the shaving blade near the tail end has a second groove, and the second groove matches the second convex point. When assembling the blade of the shaving tool, firstly extend the front end of the shaving blade into the front end of the blade slot of the blade holder, so that the first groove of the shaving blade corresponds to the first convex point of the blade holder, and then rotate the tail end of the shaving blade and insert it into the blade slot, so that the second groove of the shaving blade corresponds to the second convex point of the blade holder, so that the shaving blade is clamped in the blade slot of the blade holder. When removing the blade, just pull the tail end of the shaving blade out of the blade slot of the blade holder with force, and the shaving blade can be easily removed. It can be seen that the shaving tool with replaceable blades of the utility model can not only replace the blades, but also can well clamp and fix the blades by using the two protrusions on the blade clamp to cooperate with the two grooves on the shaving blades, thus preventing the blades from slipping out, making the blades more stably fixed and having a good operating feel. Moreover, the stability of such clamping and fixing is not affected by the use time, and has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0018] like Figure 1 , Figure 2 and Figure 3As shown, the shaving tool with replaceable blades of the utility model comprises a handle 1, a blade clamp 2 is fixed at the front end of the handle 1, and a shaving blade 3 is arranged in the blade clamp 2. The lower end of the blade clamp 2 has a blade slot, the inner edge of the front end of the blade slot has a first convex point 221 extending downward and inward, and the upper edge of the rear section of the blade slot has a second convex point 222 extending into the blade slot. The shaving blade 3 is in the shape of an elongated strip, and the upper part of the front end thereof has a notch, and the bottom of the inner edge of the notch has a first groove 31, and the first groove 31 is matched with the first convex point 221. The upper part of the shaving blade 3 near the tail end has a second groove 32, and the second groove 32 is matched with the second convex point 222. The lower part of the tail end of the shaving blade 3 has a third groove 33, and the lower part of the third groove 33 is located outside the lower edge of the blade clamp 2 in the installed state.
[0019] In order to facilitate processing and assembly, the blade clamp 2 includes a left clamp 21 and a right clamp, and there is an intermediate fixing piece 22 between the left clamp 21 and the right clamp, and the three are fixedly connected, and the thickness of the intermediate fixing piece 22 is equal to the thickness of the shaving blade 3. The upper edge of the intermediate fixing piece 22 is flush with the upper edges of the left clamp 21 and the right clamp, and the lower edge of the intermediate fixing piece 22 is higher than the left clamp 21 and the right clamp, so as to form the blade slot. The front end of the intermediate fixing piece 22 extends downward and inward, so as to form the first convex point 221, and the rear section of the intermediate fixing piece 22 has a downward convexity, so as to form the second convex point 222.
[0020] The tail end of the blade clip 2 extends into the front end of the knife handle 1, and the two are fixedly connected. The lower front end of the knife handle 1 is provided with a clearance cavity 13 for loading and unloading the shaving blade 3.
[0021] The handle 1 is composed of a left handle unit 11 and a right handle unit, and the left handle unit 11 and the right handle unit are fixedly connected by rivets or bolts.
[0022] Preferably, the tail end and the middle part of the left handle unit 11 and the right handle unit are connected by rivets or bolts, the front ends of the left handle unit 11 and the right handle unit are connected by bolts, and there is an arc notch 223 on the middle fixing piece 22 corresponding to the bolts at the front ends of the left handle unit 11 and the right handle unit. In this way, the clamping force of the left clamping piece 21 and the right clamping piece on the blade clamp 2 on the shaving blade 3 can be adjusted by rotating the bolts at the front ends of the left handle unit 11 and the right handle unit, thereby avoiding the over-tightening or under-clamping caused by the processing error of the thickness of the shaving blade 3, or the loosening of the clamping piece caused by long use time, so that the fixing of the shaving blade 3 is more stable and reliable.
[0023] When assembling the blade of the shaving tool with replaceable blades of the utility model, firstly, the front end of the shaving blade 3 is extended into the front end of the blade groove of the blade clamp 2, so that the first groove 31 of the shaving blade 3 corresponds to the first convex point 221 of the blade clamp 2, and then the tail end of the shaving blade 3 is rotated and inserted into the blade groove, so that the second groove 32 of the shaving blade 3 corresponds to the second convex point 222 of the blade clamp 2, so that the shaving blade 3 is clamped in the blade groove of the blade clamp 2. When removing the blade, it is only necessary to pull the tail end of the shaving blade 3 out of the blade groove of the blade clamp 2 with force, and the shaving blade 3 can be easily removed. It can be seen from this that the shaving tool with replaceable blades of the utility model can not only replace the blade, but also use the two convex points on the blade clamp 2 to cooperate with the two grooves on the shaving blade 3, so that the blade can be well clamped and fixed, and the phenomenon of the blade sliding out is prevented, so that the fixation of the blade is more stable and the operation feels good. Moreover, the stability of this clamping and fixing is not affected by the use time, and has a long service life.
