Abstract
The utility model provides an adjustable hand steel saw frame, which belongs to a tool. The utility model is provided with a pipe frame with inner screw threads, and the pipe frame and the other pipe frame with outer screw threads are arranged together. A transverse groove is arranged on the other pipe frame, screw bolts pass through the transverse groove and then are arranged on two pipe frames, and the end part of every pipe frame is provided with a handle. The end part of the other pipe frame is provided with a saw blade fixed pin shaft, a pin is arranged on the fixed pin shaft, and the lower surface of the pipe frame is provided with a supporting rod. The other fixed pin shaft is arranged on the supporting rod, and two ends of the other fixed pin shaft are respectively provided with a fine tuning nut and the other pin. The hand steel saw frame has the advantages of simple structure and low cost, and the length of a saw frame is adjusted by rotating the pipe frame through screw threads. After positioning, the integrity of the hand steel saw frame is strong, so rigidity is enhanced, and the problems that the original hand steel saw frame jumps the groove, and the saw blade is broken are effectively avoided. At the time of sawing, the swinging amplitude of the saw blade is small to realize vertical sawing.
Description
Technical field
The utility model provides a kind of instrument, especially a kind of improved hand hacksaw frame.
Background technology
At present, on the used hand hacksaw frame of people, have the end to be sleeved on together two hack levers, a plurality of (being generally 3) notch is arranged on one of them hack lever, there is a projection end of another hack lever.By this projection is stuck in the notch of diverse location, change the length after two hack levers are sleeved on together, to adapt to the saw blade of different length.This hand hacksaw frame rigidity is low, when carrying out sawing behind the installation saw blade, notch and the phenomenon that projection breaks away from often takes place, and is commonly called as job-hopping.Can cause fractureing of saw blade like this.Both needed to change saw blade, lose time, influenced the quality of sawing again.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of hand hacksaw frame of regulating is provided, to avoid job-hoping and the generation of breaking saw blade problem.
The utility model is to realize like this, can regulate the hand hacksaw frame, it has tapped pipe support, pipe support be with externally threaded another pipe support to be installed together, on another pipe support translot is arranged, bolt is installed on two pipe supports after passing translot, and the end of pipe support is a handle, and the end of another pipe support is equipped with the saw blade fixed pin shaft, pin is arranged on the fixed pin shaft, pole is arranged below the pipe support, another fixed pin shaft is arranged on the pole, another fixed pin shaft two ends have fine-tuning nut and another pin respectively.
Adopt the hand the regulated hacksaw frame of said structure, simple in structure, low cost of manufacture.The adjustment of saw frame length is rotated pipe support by screw thread and is got final product.Behind the location, the globality of hand hacksaw frame is strong, thereby has improved rigidity, has effectively avoided the job-hopping that original hand hacksaw frame takes place and the problem of breaking saw blade.The amplitude of fluctuation of saw blade is little during sawing, can realize vertical sawing.
Description of drawings
Fig. 1 is that the master of the utility model structure looks schematic diagram.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the schematic diagram of another fixed pin shaft structure in the utility model.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model and operation principle.
As shown in drawings, the utility model can regulate the hand hacksaw frame, it has tapped pipe support (1), pipe support be with externally threaded another pipe support (4) to be installed together, translot (2) is arranged on another pipe support, bolt (3) is installed on two pipe supports after passing translot, the end of pipe support (1) is handle (10), the end of another pipe support is equipped with saw blade fixed pin shaft (6), pin (7) is arranged on the fixed pin shaft, pole (11) is arranged below the pipe support (1), another fixed pin shaft (55) is arranged on the pole, another fixed pin shaft two ends have fine-tuning nut (9) and another pin (8) respectively.
During use, take off bolt (3), rotate the position of pipe support, install bolt (3) again and tighten, realize the location of two pipe supports to the length of saw blade that is fit to be installed.Then, the hole by the saw blade two ends is installed in saw blade on the pin on two fixed pin shafts.By rotating fine-tuning nut, make saw blade have suitable elasticity, can carry out sawing.Because the length of each saw blade is full-length, length that can be by setting two pipe supports, the pitch of screw thread and the position of the screw of construction bolt (3) above the frame pipe (1), after the frame pipe was rotated, the screw of the construction bolt (3) on the frame pipe (1) was just in time aimed at the translot (2) on another pipe (4).
Claims (1)
1, can regulate the hand hacksaw frame, it is characterized in that, it has tapped pipe support (1), pipe support be with externally threaded another pipe support (4) to be installed together, translot (2) is arranged on another pipe support, bolt (3) is installed on two pipe supports after passing translot, the end of pipe support (1) is handle (10), the end of another pipe support is equipped with saw blade fixed pin shaft (6), pin (7) is arranged on the fixed pin shaft, pole (11) is arranged below the pipe support (1), another fixed pin shaft (5) is arranged on the pole, another fixed pin shaft two ends have fine-tuning nut (9) and another pin (8) respectively.
