The utility model discloses a laborsaving food chopper which comprises a box body, a pressing plate and a pressing block, a cutter is arranged on the box body, a hinge seat is arranged at the rear end of the box body, the pressing plate is provided with a connecting end and a free end, the connecting end of the pressing plate is pivoted to the hinge seat of the box body so that the pressing plate can rotate relative to the hinge seat, one end of the pressing block is pivoted to the hinge seat, and the other end of the pressing block is hinged to the hinge seat. The other end of the pressing block is movably connected to the pressing plate through a connecting arm, and the pressing block is provided with a pressing die part; the pressing plate, the pressing block and the connecting arm are matched to form a labor-saving composite lever mechanism; when the pressing plate rotates towards the direction close to the cutter relative to the hinge seat, the pressing plate acts on the pressing die part through the composite lever mechanism, so that the pressing die part is matched with the cutter to cut food, and through the arrangement, the food can be cut in a more labor-saving manner.

The utility model relates to the technical field of tire testing, in particular to a tire pinning testing device. The testing device comprises a rack, a testing rotating shaft which rotates on the rack and is used for coaxially assembling a to-be-tested tire, a testing nail assembly which is driven by an operation part and can be inserted into and far away from the to-be-tested tire, and a ratchet mechanism which can drive the testing rotating shaft to do equal-angle stepping rotation in a unidirectional intermittent manner, a transmission ratchet wheel of the ratchet wheel mechanism is coaxially fixed on the test rotating shaft, and a pawl of the ratchet wheel mechanism is in transmission fit with the operation part through the linkage mechanism and drives the transmission ratchet wheel to generate one-time stepping rotation action in a motion period that the operation part drives the test nail assembly to be inserted and then is away from the to-be-tested tire to reset. According to the utility model, the linkage matching between the nail driving structure and the tire rotating structure can be realized, the cost is low, the arrangement uniformity of puncture holes in the tire can be ensured, and the consistency of data of adjacent tests is further maintained.

The utility model provides a kind of tool for steel plate straight probe ultrasonic testing, including tool base, the top central part of tool base is fixed with the straight probe pedestal for installing straight probe, the outside of straight probe pedestal is equipped with limit sleeve;Tool base top is hinged with extension rod connecting frame, the end of extension rod connecting frame is used to connect extension rod;The inner bottom of tool base is installed with ball by ball fixed buckle rolling limit, ball protrudes tool base certain height and with the surface of the steel plate to be detected rolling contact cooperation.This tool can be used for reliable positioning installation straight probe, and can be conveniently connected extension rod, and then conveniently assembled to form entire ultrasonic testing tool to realize the ultrasonic detection of steel plate, while effectively reduce the friction between steel plate in detection process, play good labor-saving effect, reduce detection operation difficulty, improve detection efficiency.

The utility model belongs to the technical field of doors and windows, and provides a side pressure door and window translation device and a pulley device, the translation device comprises a first support, a second support and a translation driving assembly; the translation driving assembly comprises a swing arm, a driving piece and a driven piece; the swing arm is rotationally connected to the first support, a driving groove is formed in one side of a rotary connecting point of the swing arm, and a sliding fit groove is formed in the other side of the rotary connecting point of the swing arm and connected with a driven piece. The first support is provided with a first guide groove, and the driven part penetrates through the first guide groove and then is connected with the second support. The driving part moves in the length direction of the sash frame along with a transmission strip of the hardware system, the extending direction of the driving groove inclines relative to the moving direction of the driving part, the extending direction of the sliding fit groove is horizontal relative to the length direction of the swing arm, and the driving part is matched with the driving groove to promote the swing arm to rotate when moving. According to the utility model, the force for locking the door window sash by a user is reduced, the hand feeling is improved, and the reliability is good.
