Abstract
The invention discloses a multifunctional angle grinder achieving an automatic protection function when the angle grinder slips out of the hand. According to the multifunctional angle grinder, a grinder head is arranged on the front side of a grinder body, a motor is installed in the grinder body and internally provided with a motor shaft, and a worm is arranged at the front end of the motor shaft; the grinder head is internally provided with a worm gear, a worm gear shaft is installed in the worm gear, the worm gear is engaged with the worm, and saw blades are installed at the front end of the worm gear shaft; a shaft sleeve is arranged on the outer side of the worm gear shaft, a protective cover connecting bearing is arranged on the outer side of the shaft sleeve, a protective cover is arranged on the outer side of the protective cover connecting bearing, and a protective cover handgrip is arranged on the outer side of the protective cover; a main handle is arranged at the upper end of the grinder head, an automatic power-off switch is arranged on the front side of the main handle, and a power source connecting wire is installed at the back end of the grinder body; when the angle grinder slips out of the hand in the using process, the protective cover is rapidly closed under the action of the tensile force of a reset rubber band, and the saw blades of the angle grinder are blocked, so that the situation that people are hurt by the saw blades is avoided; and the automatic power-off switch installed on the front side of the main handle is disconnected instantaneously at the same time, a power source is cut off, and hence the personal safety is ensured.
Description
The field of inventionthe invention relate to a kind of small-sized cutting tool, be specifically a kind of automatic shielding angle grinding machine of slipping out of the hand with several functions.
Background technology angle grinding machine is a kind of small-sized electric tool, has cutting and the dual-use function of polishing, in machining, purposes is widely, but owing to angle grinding machine volume is little, moment of torsion is big and rotating speed is high, the accident of slipping out of the hand often occurs during operative, and once slip out of the hand, owing to the power supply of angle grinding machine cannot cut off, bringing great injury to operator, the lighter cuts off foot muscle or hamstring, severe one is also opened the broken tripe of intestinal, even abandons life.
The summary of the invention therefore people angle grinding machine to protection automatically of slipping out of the hand; there is great demand, up to now also without finding the relevant report about the present invention, the present inventor is through research experiment repeatedly; finally the angle grinding machine that developing slips out of the hand can protect automatically, thus completing the present invention.
It is an object of the invention to provide a kind of automatic shielding angle grinding machine of slipping out of the hand with several functions, to prevent industrial accident, it is ensured that the life security of operator.
The solution of the present invention includes: body, head, motor, worm screw, worm gear, worm-wheel shaft, saw blade, protective cover and protective cover hands handle, it is structurally characterized in that and is provided with head in the front side of body, described body is a circular long column body, body can use as secondary handle also known as secondary handle, body is built with motor, being provided with motor shaft in motor, the front end of motor shaft is provided with worm screw.Being provided with worm-wheel shaft in head, equipped with worm gear on worm-wheel shaft, worm gear and worm engaging, the front end of worm-wheel shaft is equipped with saw blade.Worm-wheel shaft outside saw blade is provided with axle sleeve, and the outside of axle sleeve is provided with protective cover and connects bearing, and protective cover connects the outside of bearing and is provided with protective cover, and protective cover is weldingly fixed on protective cover and connects in the outer rim of bearing, is connected bearing outer rim with protective cover and is connected as a single entity.The outside of protective cover is provided with protective cover hands handle, the lower end of protective cover hands handle is weldingly fixed on protective cover and protective cover is connected as a single entity, the downside of head is provided with joint pin, and joint pin is fastened on protective cover on the handle equipped with the other end of return spring or rubber band, rubber band or return spring.The upper end of head is provided with main handle, and the front side of main handle is provided with automatic power-off switch, and the rear side of main handle is provided with on power line designated lane.The inner side of secondary handle is provided with under power line designated lane, and the rear end of body is equipped with electric power connection line.
During operation, protective cover hands is connected as a single entity with main handle pulling to main handle, grasp main handle and protective cover hands handle, carry out cutting or polishing operation, when angle grinding machine is in use slipped out of the hand, protective cover hands protective cover out of hand under the pulling force effect of back-moving spring or rubber band, rapid closing, block angle grinding machine saw blade, it is to avoid saw blade is hurted sb.'s feelings.It is simultaneously attached to the automatic power-off switch moment disconnection on front side of main handle, cuts off the electricity supply so that it is shut down.
Present configuration is simple, designs ingenious, easy to operate, uses safety.
